The initial incident was failed timing chain tensioner guides. As indicated earlier Nissan knowingly redesigned the parts since the originals were found to wear through, causing the timing chain to rub directly on the metal post of the tensioner and contact the housing cover. During the repair the Nissan service department confirmed the failed radiator coolant contamination addressed in ODI NHTSA action number: DP12004. The timing chain and guides were replaced; the radiator was replaced; coolant was flushed; transmission was drained, flushed, and filled. The service department also confirmed Nissan, N.a. would not offer any amount of repair assistance. Total cost was $2200. The day after the vehicle was repaired it suddenly decelerated from 55mph to 30mph and the RPM's increased to 4K+ while traveling on a multi lane dark country highway at 11pm. The section of highway did not have an emergency lane or shoulder. A vehicle was in the left lane and a semi-truck was quickly approaching from the rear in the right lane. Once crossing the bridge the vehicle was jerked to the shoulder, avoiding a rear collision from the approaching semi-truck. The vehicle was turned off and restarted. The RPM's returned to 1K, the transmission was in neutral, and the check engine was illuminated. The following day Nissan service confirmed it was a failing valve body as a result of the coolant contamination. The wholesale repair cost was quoted at $1400. Again, Nissan, N.a. would not address the failure. At this time the repair has not, and will not, be completed.

Engine coolant is leaking into transmission. I am experiencing the same exact situation as the current investigation that is happening over the last two years.

Check engine light came on, took to mechanic for a check and found that we were leaking radiator coolant into the transmission fluid. Had to replace parts and flush transmission at a pricey cost.

Began hearing a whining noise from engine, increasing with RPM. Took to dealership, who indicated it was bad timing chain tensioner shoes/guides. Service advisor indicated this is a very common issue, and Nissan redesigned the parts since the originals were found to wear through, allowing the timing chain to rub directly on the metal post of the tensioner. The timing chain system should last for the life of the engine, not require a $1700 repair only about halfway through the engine life. This is also a very unsafe situation, since a timing chain failure could quickly destroy the engine, leaving the car without engine power out on the road. This should be a recall.

Vehicle suddenly stopped changing gears while on a main road where speed limit is 55 mph. Turned onto a smaller country road, could not accelerate more than 20 mph, and slowly descended from there until finally coming to a complete stop. Cracked radiator caused coolant leak into transmission fluid causing many systems to fail. In turn, had to replace radiator and completely rebuild and flush transmission several times ($4400 expense). Had I been on a major highway or interstate when this happened, there would have been a much more serious out come.

While driving 70 miles an hour on the highway my car suddenly shot up to 4000 RPM and wouldn't go faster than 30 miles an hour. After my car was towed to a local mechanic friend of mine's shop he told me the radiator had cracked, leaked coolant into the transmission, fried the transmission and torque control valve, all valves and seals, as well as both catalytic converters. The cost to fix would be $6000. Nissan needs to pay for this because of their factory defect!!!

Check engine light came on so I took it to an autozone to have the code read. PO463, fuel sending unit. Did some research, called Nissan corporate to inform them of the issue and see if I was eligible for extended warranty (wasn't covered). Nissan corporate informed me that I was eligible for ECM relay replacement at no cost at a dealership, so I took the car to a dealership that quoted me lowest on the fuel sensor repair. They asked if I had other issues and I told them that my engine sometimes sounded like an rc car. They offered to look into it, called this afternoon after completing work on sensor and ECM relay to inform me that my timing chains were shot and in need of immediate replacement. Did some more research and found this is a frequent issue in Nissan cars, decided to file a report

The radiator leaks coolant into the transmission. Consequently both the transmission and the radiator has to be replaced.

I was driving on a regular one way street, when my check engine light came on and smoke came from under the hood. By the way, this happened on my wedding day. Anyyways, I had the car towed to a car shop to find out the radiator bursted causing the coolant and transmission fluid to mix, my transmission is ruined and needs to be replaced, my radiator needs to be replaced, the fluids got into my water pump which also needs to be replaced. The complete cost for damages is $7500. Now I am out of a car and cant trade it in because it is not worth anything at this point. After reading all the complaints I see many others have faced this problem, there needs to be a recall on these faulty radiators in the 2006 Nissan Xterras.

There was recall for vehicles similar in year as my car. The recall was # 10V517000 and was for the "intelligent power distribution module (ipdm)". I called Nissan America, and although many vehicles of my year and make/model were affected, my VIN # was not included. I should have been included on this recall because this is exactly what part was defective and exactly what I had to pay for to get fixed. I was even driving when it stalled out on me numerous times and I am thankful it was not on the freeway. If possible I would like to be acknowledged and potentially be reimbursed by Nissan.

While on a business trip away from home noticed the heater stopped blowing warm air. A few minutes later engine temperature spiked but then returned to normal. 50 miles later heater started working again. Took the car to a local mechanic and discovered transmission cooler within the radiator had failed, allowing the radiator coolant to mix with the transmission fluid. Paid for the replacement of the radiator/transmission cooler, system flush. Had the system flushed again 1 week after radiator replacement. Transmission now acting erratically, particular when shifting between 3rd and 4th gear. Initial assessments by mechanic suggests transmission and transmission computer require replacement. Cost of replacement exceeds the value of car even though the rest of the car is in excellent condition.

The contact owns a 2006 Nissan Xterra. The contact stated that while driving approximately 65 mph, the engine stalled without warning. The vehicle failed to restart and was coasted to a safe location. The vehicle was towed to an authorized dealer where the ECM relay was replaced. In 2011, the vehicle was repaired under NHTSA campaign id number 10V517000 (engine and engine cooling). The contact had not previously experienced a failure at the time the vehicle was repaired under the recall. The manufacturer was notified of the problem. The approximate failure mileage was 68,000. The VIN was unavailable.

Nissan will not step up and fix their mistake, our car is at 87000 miles and the coolant is leaking into the transmission due to how Nissan configured their system from the years of 2006 - 2009. When I spoke with [xxx] at Nissan Consumer Affairs he intimated that Nissan is not aware of this being a major issue, but interestingly enough stopped using this configuration in 2010. They claim that it will not happen to every Nissan, we need more consumers to come forward, so that this will become a "recall". the system is faulty it may not happen at 80,000 / 90,000 / 100,000, but count on it happening at some point. This is a very expensive repair. If Nissan had communicated to us that the warranty covering this transmission failure was extended to 80,000 but of course why would they admit to a faulty system, and let their valued customers know. Simple they do not value their customers, they lost this group. Way to go Nissan, somewhere down the line this will hurt you.

Started over a year ago that while driving the motor would just stop running, would have to coast to the side if the road without power steering or brakes. I took it into the shop and they couldn't find out the problem. Now that my transmission is starting to shake and make noise, I took it to the dealer. They told me that my radiator is making into the transmission and that makes the motor quit and loss of power. I am informed that I need a new radiator and transmission. Looking online I see that there are a lot of people with this sane safety issue and that there is no recall. I think that there should be a recall because it's safety alone! I almost hit a car and a pedestrian while trying to steer off the road and stop. Please help with a recall!!

The transmission started to slip, turns out the atf was contaminated by the radiator failing and leaking coolant into the transmission. This was determined by the dealer and of course it was out of warranty. I replaced the radiator and the transmission is being worked on by a transmission shop to the tune of several thousand dollars. The contamination ruined at least all clutch plates, the bands, and the torque converter.
